    Production of single cell protein from bowels and viscera of tuna fish by Bacillus sp. (2018)
    Details
    Publication Date: 2021-05-19
    Description: In this research, were used from Bacillus licheniformis and Bacillus subtilis (spore-forming gram positive bacteria) for single cell protein production from tuna fish viscera (Thannus tonggol). Examination was done in two laboratory and fermentor scales. The used fermentor was Continues Stirred Tank Reactor (CSTR). Influence of several parameters such as pH, temperature, rpm, and fermentation time was evaluated on SCP production process. The result showed that value of SCP was 30- 45 g/l of aliquot substrate. Growth of isolates in 35°C and pH=6.9 were more than 32°C pH=6.5. Time fermentation in lab and fermentor scales was 54h and 21h respectively. Production of SCP in rpm =600 in fermentor scale was more than rpm=300. With complementary examination, can be used from SCP produced from tuna viscera, as probiotic, in fish feed.

    Evaluation of quantitative and qualitative of microbial indicator the lake behind Shahid Rajaee dam of Mazandaran province (sari) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: One of the country's dams is dam Shahid Rajaee Sari. In this study it was evaluated some bacterial indices. Some bacterial parameters including total bacteria, total coliform, fecal coliform, fecal streptococci , Sulphitereducing Bacteria (SRB) in the water behind the dam Shahid Rjaee for one year at five stations (the entrance Shireenrood branches, input branch of the Sefidrood, cross the river and sweet Sefidrood in the tank, close to the Taj (zero, 15 and 30) and the output reservoir) and seven samples collected during six periods (June, July, August, September, November and February) were tested in 1391. Analysis of water samples for bacterial plate count agar medium (total bacteria count) ECC were inoculated (total coliforms and fecal), SPS (sulfite reducing bacteria) and KF (bacteria Inserts fecal streptococci) was performed using the culture surface culture method. ECC in both 37 and 44 ° C medium temperature Tc, KF and SPS at 37 ° C for 72-24 hours were incubated. The results showed that the mean log of bacteria in different months of CFU / 100ml12 / 0 ± 85/6 1n September months to CFU100ml15 / 0 ± 65/4 is variable in February, the mean total coliform Log in of the CFU / 100ml15 / 0 ± 63/4 in September to CFU / 100ml44 / 0 ± 27/3 in February are variable, the mean log Clostridium Clostridium CFU / 100ml89 / 0 ± 17 / 4 in September to CFU / 100ml13 / 0 ± 07/3 in February is variable, ranging from the mean log reduction in fecal streptococci in different months CFU / 100ml19 / 0 ± 59/3 in September CFU / 100ml17 / 0 ± 10 / 3 in February is variable. The results showed that bacterial indicator pollution load of the dam in more stations in August and September months. . Compare the results of the surface water standards indicate that indicator bacteria have been studied in the standard range. If the water behind the dam is intended to be used for drinking, it has need for more treatments during the final purification for drinking purposes.

    Study of indicator bacteria and ovary of nematode at the surface water, underwater and sewage in the basin of Mangol dam (Mazandaran province) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Indicator of bacteria such total coliforms and fecal coliforms are one of the most important environmental factors that effect on water quality. Haraz river is one of three rivers in north of country and it originate from central Alborz. Overall, discharge of unborn sewage, agriculture pesticides, seasonal raining was caused decreasing of quality of the river. Therefore, quality and quantity of the grandwater, surface water and sewage in different zone of this river such Mangol dam is necessary. In this study, total coliforms and fecal coliforms and nematode ovary in 13 stations of Haraz including Sorkhrood, Klodeh, Amol Esar Town, Helomsar, Mangol dam, Karesang, Jalav bridge, Norroud, Tehran 115, Larijan, Abeask, Lasem, Lar (pleur) were surveyed. ECC Chrome agar was used for counting and isolation of coliforms groups and nematode ovary counting was done as formal – ether sedimentation method. The results showed that maximum and minimum of total coliforms in surface water was observed in Sorkhrood (9.4 CFU/100ml) and Lasem (4.2CFU/100ml) and also maximum and minimum of fecal coliforms in Sorkhrood (3/2 CFU / ml) and Lasem (1/1CFU/100ml) respectively. Maximum and minimum of these bacteria in ground water were Abeask (4 CFU /100ml) and Helomsar (9/1 CFU/100ml) (for total coliforms) and Abeask (7/1 CFU/100ml) and Helomsar, Klodeh and Larijan (2/1 CFU/100ml) (for fecal coliforms) respectively. Maximum and minimum of total and fecal coliforms in sewage were Norroud (1/3 CFU/100ml) and Amole Esar Town (2/2 CFU/100ml) (for total coliforms) and Norroud (6/1 CFU/100ml) and Amole Esar Town and Tehran 115 (2/1 CFU/100ml) (for fecal coliforms) respectively. Ovary of Nematode in sewage was 30 and 124 in Norroud and Amole Esar Town respectively. The conclusion of this study was showed that quality of Haraz is low level and not proper for drinking and swimming.
